Using pipistabrowsing

So im hearing a lot about pipista and its ability to install other modules. I want to install nltk or mathplotlib with pipista. Van someone tell me where to get pipista, and how to put it onto pythonista and how to run it to get libraries from the pypi library

hmmm. The first time I tried pipista it told me that it download the .gz file, but when I tried shellista it couldn't find the file. But I tried it again and it worked just great. So not sure what happened.

For future generations who find themselves here.. pipista is no longer supported. Active development is happening on stash https://github.com/ywangd/stash, which includes a pip command that is a little more reliable.
